What is BS EN ISO 9241-317:2013

BS EN ISO 9241-317:2013 is an international standard that provides guidelines for the design and evaluation of human-system interaction in interactive systems. It specifically focuses on the usability aspects of user interfaces, aiming to enhance user experience and ensure efficiency in system operation.

The Importance of User-Centered Design

User-centered design, as emphasized in BS EN ISO 9241-317:2013, is a fundamental principle that prioritizes the needs and preferences of users during the development of interactive systems. By considering users' cognitive abilities, physical characteristics, and task requirements, designers can create interfaces that are intuitive, efficient, and satisfying to use.

Guidelines for Interface Design

This international standard outlines several guidelines for interface design.

Firstly, it suggests that designers should provide appropriate feedback to users, informing them about the system's status, actions taken, and possible errors. Clear feedback helps users understand the outcome of their actions and prevents confusion or frustration.

Secondly, BS EN ISO 9241-317:2013 recommends consistency in interface design. Consistent appearance, behavior, and terminology facilitate user learning and reduce the cognitive load required to operate the system.

Thirdly, the standard highlights the importance of error prevention and recovery. Well-designed interfaces should minimize the occurrence of errors and provide easy-to-understand instructions or options for users to correct their mistakes.

Additionally, the standard emphasizes the need for effective information presentation. Designers should organize information in a logical and meaningful manner, considering users' mental models and the tasks they need to accomplish.

Evaluating User Interfaces

BS EN ISO 9241-317:2013 also provides guidance on the evaluation of user interfaces. It recommends a combination of objective measurements, such as task completion time and error rates, and subjective assessments through user feedback or interviews.

Regular evaluations allow designers to identify usability issues and make necessary improvements to enhance the overall user experience. This iterative process helps create user-friendly interfaces that meet the requirements and expectations of their intended users.

Overall, BS EN ISO 9241-317:2013 plays a crucial role in ensuring the design of interactive systems that prioritize usability and user satisfaction. By following the guidelines outlined in this international standard, designers can create interfaces that are efficient, effective, and enjoyable to use.
